SPECIFICATION forming part of liletters. Patent No. 634,074, dated October 3, 1899.

Application led May 19,1898. Serial No. 681,120. (No model.)

To all whom t may concern.-

Beit known that we, DENNIS E. VIRTUE and n MARTIN DEEG, citizens of the United States,

residing at Owatonna, in the county of Steele and State of Minnesota, have inventedcertain newand useful Improvements ina Combined Chnrn and Butter-Worker; and we do hereby declare the following to be a full, clear,

Our invention relates to combined churns and butter-workers, and has for its object to provide an improved machine of this class.

To this end our invention consists 'of the -novel devices and combinations of devices hereinafter described, andV defined in. the

claims. 1 Y The invention is illustrated in the Vaccompanying drawings, wherein like notations refer to like parts throughoutthe several views. l'

Figure 1. isanendfelevati'onof vour improved machine'with some parts removed.` Fig. 2 is a longitudinalvetical. section through the same von theline x? .niet Eig; 1;-

Fig. 3 is a vertical cross-section on the line ac3 we. of Fig. 2. Fig. et is'a section on the line x4 x4 of Fig.'1' when the'drnm is. in position to bring the working rollers one directly over the other in the verticalplane. Fig. 5 is a detail showing the shipper-fork for the rollerdrive detached, and Fig. 6 is an end view of the roller-drive with the other parts removed.

The drum 1 is mounted in any suitable way to receive rotary motion from any, suitable drive. As shown, the drumfheads arev provided with trunnion-spiders 2, the trunnions of which rest in suitable bearing-pedestals 3, fixed to the ioor or other supporting-base. One of the trunnions-to wit, the right-hand member, as shownis hollow for a purpose which will later appear. The drumLheadfacing the hollow trunnion is shown as provided with an internal gear-wheel 4, which -diametrically opposite to` each other. single pair. of the `perforated blades 10 are which motion is imparted by a belt from any suitable source.

The drum lis provided on its interior with a series 'ofbeater-blades '9 and 10. Of these beater-blades the members 9 are narrower than. the members 10 and are imperforate.

The members 10 are wider than the members 9 and are provided with a series of holes 11. All of said beater-bladesQ and 10 are set radially inward from the shell of the drum, so as to leave clearance behind the same or, in other words, between the same and the concave cylindrical surface of the drum. The beaterblades are secured at their opposite ends to the drum-head. The perforated beater-blades 10 are arranged in pairs, which are substantially j Only a shown, while all the others are solid;rbut an additional pair of the perforated blades might be'empl'oyed, if sodesired. Thedrum is also provided onits interior with a pair of corrugatedwcrkingrollers 13, journaled in the 'drum-heads. The. journals of these rollers 13 extend outward at o'neendvthrough the drum-head and are provided at their outer ends with pinions 14.*- The said journals of thev rollers 13 pass outward through suitable stuffing-boxes 15 to preserve a tight joint.v The pinions 14 on the working rollers 13 are respectively engagedeach by one member of a pair These double gears are carried' shown as headed at their cuter ends to. limit the outward movement of the said double gears. `The stud-shafts Y18 and the double gears carried thereby are located diametri@- ally opposite to each'otherand equidi'stant from the axis of the drum. The hubs of said double gears. are.. engaged by thek opposite forks of a shipper-head19, having acentral stem 20, which passes outward through the .hollow trunnion of the drum and is engaged by a hand-lever 21, (shown as pivoted at its lower end to a bearing-lug 23,) projecting from the pedestal 3. Under the action of the hand-lever 21 it is obvious that the double gearsinay be shifted on their supporting stud-shafts 18. Throughout this shifting movement, however, the double-gear members 16 always remain in mesh with the rollerpinions 14:, the latter having sufficient length of face for this purpose. When the double gears are in their outermost position, the pinion members 17 thereof will be in the proper plane to engage with a segmental rack 22, which is fixed to the pedestal 3, as best shown in Figs. 1, 2,-and 6. iVhen the double gears are shifted to their innermost position by the hand-lever 21, the pinion members 17 thereof will be in a proper plane to clear the fixed rack 22 under the rotary motion of the drum, as shown in Fig. 2. "When the double gears are in their driving position, as shown in Figs. 1 and G, it must be obvious that the pinion members 17 will engage with the iixed rack 22 in succession under the rotary motion of the drum. Hence at every shift from one to the other of said pinions 16 the inotion of the working rollers 13 will be reversed. The fixed rack 22 is preferably very nearly equal to a half-circle. Sufficient clearance must be left to permit one pinion to pass off from the rack before the other engages with the same. The motion of lthe working rollers 13 is therefore reversed twice in each revolution of the drum. These reversings come at the right times to keep the working rollers turning toward each other throughout the time that the butter is being lifted by the drum and dropped onto the working rollers. Otherwise stated, the rollers are always turning in the right direction to do their work under the continuous motion of the drum in one direction. VVithput these reversings the working rollers would half the time be turning in the wrong direction in respect to each other to do any work. By the drive above described we have provided a very simple and efficient means for driving the said working rollers with the reversings required for the continuous working action of the said rollers.

It must be obvious, of course, that so far as the broad features of driving the working rollers with two reversings in each revolution of the drum the only essential elements are the pinions 14 on the drum-shafts, a pair of gears carried by the drum, 'and a fixed rack with which the said gears may engage in succession under the rotary motion of the drum. The addition of the pinions 17 on the same hub with the gear members 1G for engagement with the rack 22 is aconvenience for securing the desired speed to the working rollers, aud the addition of the shipper-head with the gears mounted to slide on the stud-shafts carried by the drum is a further convenience into and out of action is of course desirable in a machine of this kind, which is first used to churn the cream to separate the butter and then to work the butter. When the machine is used for churning, the working rollers are left in their idle position. When used to work the butter, they are thrown into their operatieve or driving position. It will also be understood, of course, that the drum might receive its rotary motion in any other suitable Way instead of' by the means shown and described.

The churning and working actions of a machine of this class are of course well understood, and it is not deemed necessary to detail the same for the purposes of this case.

What We claim, and desire to secureby Letters Patent of the United States, is as follows:

1. In a combined churn and butter-worker, a rotary drum or shell having a pair of butter-Working rollers provided With operatinggearing and located respectively at equidistant points on opposite sides of the drums axis and geared to turn together to work the butter between them, in combination with a single fixed segmental rack adapted to be successively engaged by the operating-gearing of each roller and from which said rollers are alternately driven in reverse directions in succession under the continuous rotation of the drum, whereby said working rollers reversing twice in each revolution of the drum will always turn toward each other at their upper or butter-Working surfaces.

2. In a combined churn and butter-Worker, the combination with a rotary drum having a pair of Working rollers therein, with their shafts extended,at one end,through the drumhead, of a reversing-drive for said rollers comprising intermeshed pinions on said projecting shafts, a pair of gears carried by the drum, one engaged by each of said pinions, and a fixed segmental rack adapted to be engaged by said gears, in succession, under the rotary motion of the drum, substantially as described.
